LAMP-SUPPORT.-

Specification of Letters Patent.

Patented July 20, 1920.

Application filed February 21, 1919. Serial No. 278,497.

To all whom it may concern:

Be it known that I, FRANCIS M. ROSEN- FELD, a citizen of the United States, and a resident of the city, county, and State of New York have invented an Improvement in Lamp-Supports, of which the following is a specification.

The present invention relates to an improvement in lamp supports and has application more particularly to lamps of the character commonly used for illuminating Christmas trees and for other decorative purposes where it is contemplated that the use shall be of a relatively temporary nature. One object of the invention is to provide a lamp support which may readily be attached to and detached from a Christmas tree or other similar object to be illuminated. A further object of the invention is to provide a support in the use of which it is possible to carry the conductors directly to the lamp without bringing them into contact with sharp edged or abrasive articles. It is also contemplated that devices embodying the present invention may permit the lamp socket to be readily attached and detached without permanently distortin or injurim the support.

An em 'odiment of my invention is illustrated in the drawin which forms a part F of the present specification and in which, 7 the single figul're is a plan view of one form of support.

- Referring to the drawing, a device embodying my invention may comprise a support for a socket 1 which is commonly provided with perforations through which conductors 2 may be inserted to provide current for an electric lamp 3 of any suitable form. For the purpose of retaining socket 1 in an upright or in any other desired position, means are provided to engage said socket and may comprise a convolution or coil of. wire 4 of suitable size and shape and preferably of such a character as to hold the socket in yielding engagement. Another coil 8 continuous with said coil 4 and eccentrically arranged with respect to the axis thereof may be provided to secure the lamp supporting coil in operative position, as on a Christmas tree branch contact insure a more secure grip upon the object to which the device is attached, and the device presents certain conveniences in operation where the axes of the two connected coils are offset and parallel.

In operation, the conductors or wires may be inserted between a free end of either of the convolutions and an adjacent portion of the spiral and by moving the convolutions of the spiral past the wire, or vice versa, by moving the wire between the convolutions of the spiral, the wire will ass longitudinally through the spiral. he socket may then be seated in enga ement with the spiral 4, and with the con uctors passing through said spiral and through the spiral 8. The latter may then be attached to the Christmas tree branch or other object to be illuminated.

In the form shown, the gripping spiral may be of large enough radius to permit the lamp socket to be passed through it.

The wires will pass longitudinally through the gripping spiral without coming in contact with any abrading or cutting surfaces and the lamp, together with its support, may be attached in any desired position without danger of exposing a live wire or short circuiting the lamp.

Where the socket supporting portion is offset from the support gripping portion, a

convenient device is providedfor varymg' the placing of fanciful lights such as those simulating fruits, animals and the like.

I claim as my invention- 1. A lamp support comprising convolutions in a continuous strip of wire forming in part a spiral gripping coil and in part a spiral lamp holding c011, said lamp holding coil being arranged eccentrically with respect to said gripping coil and with its axis parallel to the axle of said coil, and positioned to hold a lamp entirel at one side of the axis of the gripping ooi 2. A lamp support comprising two coils arranged end to end in a continuous strip of wire, the diameter of one coil being greater than that of the other coil, said coils having parallel axes and being disposed eccentrically with respect to each other.

In testimony whereof I have signed my name to this specification this 31st day of January, 1919.

FRANCIS M. ROSENFELD.
